“So embarrassing,” Troye laughed when Jimmy held up a side-by-side pic of Justin and Troye dressed up like him.

“But like, can you believe that this is real?” Troye added. “Look at his eyebrows. Like, it’s so inspiring. Honestly, it’s so good.”

Troye also talked about the happy music he’s releasing, his film Boy Erased, the dangers of gay conversion therapy, and his work with The Trevor Project to get 50 bills in 50 states to stop the practice.

Troye and Charli also took the stage to perform “1999.”
